When President Barack Obama's motorcade pilots its way through our nation's capital today as part of his second inauguration, the world will get one of its best looks at the Cadillac limousine nicknamed "The Beast."

But President Obama's Cadillac isn't really a Cadillac. In fact, about all it shares with the crested wreath sedans you can buy from your local dealership are some styling cues. Still, The Beast is definitely a sight to behold - and there are few times it is better showcased than during an inaugural.

Not much is actually known about The Beast since it falls under the Secret Service's classified motor pool, but a few specifications and secrets have leaked out over the last few years. We pieced through what we could to provide you with this breakdown of 10 things worth knowing about Cadillac One, Limo One or... The Beast.

10 Things to Know About the President's Limo
1. It isn't a Cadillac. Unlike any presidential state car before it, The Beast shares little in common with a standard production car. Its chassis, diesel engine and transmission are based on those used in the Chevrolet Kodiak, a rugged commercial vehicle used as everything from a dump truck to a U-Haul truck.

Some standard trim pieces, like headlamps from an Escalade and tail lights from the now-discontinued STS keep it looking vaguely Cadillac-like.

2. It has its own airplane. The Secret Service makes use of a C-17 Globemaster transport aircraft to haul The Beast, a second limo and a heavily armored Chevrolet Suburban communications vehicle, any time the President is traveling. The Suburban is nicknamed Roadrunner and it is said to be a rolling communications office directly linked to a military satellite - hence the SATCOM dome festooned to its roof

3. Calling it armored is an understatement. There is probably not a better-armored vehicle with windows on the planet than The Beast. Its armor plating is said to be 8 inches thick and its doors weigh as much as those on a Boeing 757 aircraft. Five-inch thick bulletproof windows contain at least five layers to put a damper on any effort by subversives. And those gigantic, nearly bus-size Goodyear tires are Kevlar-reinforced run-flats capable of keeping The Beast on the road for quite some distance if needed. The interior is sealed off from the outside world to reduce risks of a chemical attack, while a special foam surrounds the fuel tank to insulate it in the event of an impact.

4. It's exceedingly well-equipped. Pop open The Beast's trunk and it is said that you'll find everything from firefighting equipment and oxygen tanks to a cache of the president's blood type. There are tear gas canisters, shotguns and, supposedly, grenade launchers, integrated into The Beast. The Secret Service has learned a lot since President John F. Kennedy's open-top Lincoln Continental was fired upon on Elm Street in Dallas.

5. It holds seven passengers. At the very least, The Beast has three passengers aboard - the driver, the president's lead Secret Service protective agent in the front passenger seat and, of course, the president himself. However, four additional seats in the back are available - three rearward facing spots on a bench and one spot next to the president for a guest. A folding desk separates the president from his guest's spot.

Somewhat surprisingly, the president's bench is covered in a dark blue cloth rather than leather (although plenty of hide is on board). Shoulder belts that retract toward the center of the bench and buckle into the outboard corners - the reverse of a normal rear seat - are included.

6. The Beast is not alone. The Secret Service actually has a few Beast-like vehicles. Although it's not known whether they're all functionally identical, some look more like a Cadillac DTS than The Beast. The other limousines are used for high-ranking foreign officials and VIP guests when they're in Washington, D.C. It isn't known why the Secret Service rotates between presidential vehicles, however.

In addition, the President sometimes travels in a heavily-armored Chevrolet Suburban or a modified Prevost bus known as Ground Force One rather than The Beast.

7. It runs on diesel. The Beast is believed to use a Duramax diesel engine closely related to that featured under the hood of Chevrolet and GMC's full-size heavy duty pickup trucks. Why diesel? Aside from the durability associated with diesel engines, the fuel has a low volatility that reduces the risk of it exploding - and it can be found everywhere in the world, unlike high quality unleaded fuel.

8. Its pilot is a heck of a driver. Even though The Beast has more in common with a school bus than a sports car, its highly-trained drivers can execute tight J-turns and other police-style evasion techniques in the event of a situation gone south. The Secret Service drivers have undergone extensive training on a secluded site (believed to be a military base) with input from GM engineers and test drivers.

9. Its specs will not impress you. Burdened with lugging a rumored 20,000 lbs. worth of Beast around, the diesel engine isn't a rocket. Hitting 60 mph from a complete stop takes about 15 seconds, which is more than just about any new car we can think of, and the big car's top speed is said to max out at 60 mph. In addition, all that weight makes it a guzzler, sipping fuel at a rate of 8 mpg.

10. This year, it will make a political statement. In a politically-motivated move, President Obama chose to have D.C.'s available Taxation Without Representation license plates installed on The Beast. The White House says that the decision "demonstrates the president's commitment to the principle of full representation for the people of the District of Columbia and his willingness to fight for voting rights, home rule and budget autonomy for the District."

However, it's unlikely that D.C. will gain representation in Congress as long as Republicans are in control.

Here at Leftlane, we believe the contributions of the community are just as valuable as those of our staff. The Web, at its core, is a medium for information sharing and communication. We strive to provide good information, but without you—the community member—there is no communication.

And while we have internal editorial policies governing the manner in which we share information, we have traditionally lacked similar guidelines for how our readers communicate. Lately, as our community following has increased and spread across additional platforms, it has come to our attention that we need to address this shortfall.

We want our comments section to be a healthy, vibrant forum for debate, discussion and opinion. We want to keep the tone light, conversational and if not fun, at least pleasant. We strive to keep the Leftlane platform accessible to all who wish to contribute so long as they’re willing to be civil. As such, the following behaviors will be monitored by our editorial team.

Personal insults and flaming

Debate (and even argument) is welcome, but when a conversation devolves from a conflict of beliefs or opinions into a personal grudge match, the value of that discussion is lost.

Inflammatory/offensive language

With adult conversation comes adult language, but the deliberate use of said language to offend or insult will not be tolerated.

Blatant discriminatory comments

Please check your –ist comments at the door. Genuine discussion of demographics is perfectly acceptable so long as it is substantiated by demonstrable market data, not hearsay or anecdotal information.

Spoofing/sockpuppeting

Impersonation of Leftlane readers or other figures is not acceptable. Spoof accounts may be banned without warning.

Please note that these are general guidelines. All decisions by our staff will be made on a case-by-case basis. <<Collapse
